Advice Request What is your opinion about Microsoft Windows Defender (Windows 10)?

In my case the biggest problem I've encountered is when the Antimalware Service Executable (MsMpEng.exe) uses the CPU almost 100% and this means that Windows Defender is sinking the system making it almost unusable for most of the time.

Personally I don't like windows defender.

Sure it has amazing detection rates when configured properly and has always ran pretty light on any system i've ever owned.
But there's a few things about it that i personally dont like (yes I know these are just small things, but I'm very particular)

first of all, it lacks fine built in controls, I don't like having to use a third party program to control it
Second, even with a third party application, there's no way to set it to "ask" when it detects a threat (atleast no way that I have seen)
and last, the toaster notifications for when a threat is detected on any system I have ever used has been extremely laggy
as well as it doesnt hand threats in a timely manner (I.E it takes it a bit of time to remove something as simple as the Eicar test file)

I want to like it, I really do. I've seen it come a long way. But I just cant.

That is normal when you can see Defender alerts frequently. But, for most people, such alerts are so rare that the poor GUI, lags, etc. do not matter at all.

Yes. I noticed similar behavior on one of my laptops (32 GB EMMC, 2GB RAM, Atom processor). The big CPU load is present while updating the system and Microsoft Store applications, performing system management tasks, and system scan. After that, the computer is fully usable (web browsing, watching videos, document editing). Anyway, I would prefer the Chromebook for such simple tasks.

I had a failed install multiple times. But the third time it just disappeared and my Client Version matches the current one...never seen that one.

It was being installed at the same time as the latest optional Windows Update/

I have seen some of this windows update failing reports a couple of times from several users. The issue is random it seems.

Seemed to also sort itself out quickly. So I’m not complaining.

Confirmed here it was manually updated by me on Windows Security Center
